[Mantisbt-help] Uploading files fails

[Peram's L. <per...@ho...>]

Hi,
I'm using mantis 0.17.5 on Red Hat 9 with Apache 1.3.28 and MySQL
4.0.14.  The installation is working fine. I've changed the parameters
in config_inc.php to upload files and following are the parameters
$g_allow_file_upload  = ON ;
$g_file_upload_method = DISK;
$g_max_file_size = 5000000;
$g_allowed_files     = "";
 $g_disallowed_files  = "";
When I try to upload files I get an error message 'The file type is
disallowed''.
I've tried $g_allowed_files = "php,doc,txt,xls" but in vain.
My g_register_globals = OFF ( I could not get the bug tracker with
g_register_globals = ON).

I'd appreciate if you could tell me what could be reason for this error
as I do not understand how this error message is being generated. Please
let me know if  I need to provide any further infomation.

Regards,

Peram
